Gabriel Greenfield — Transformation Powerhouse

Gabriel Greenfield is a consulting firm specialized in sovereign and responsible transformation, particularly in Data and AI, supporting organizations through an integrated, structured and responsible approach.

Our work draws on three frameworks developed in-house: the Meridian method, the GAME diagnostic, and Certified Responsible Agentic, dedicated to the governance of AI agents. Gabriel Greenfield is engaged in ISO 27001 and ISO 42001 certification processes, and applies to itself the requirements it recommends to its clients.

Meridian - Proprietary Transformation Metamodel

Meridian is our transformation method. It connects strategic ambition to operational execution through a traceability chain: Ambition, Challenges, Initiatives, KPI. This chain unfolds across five repositories: capabilities, processes, systems, data and organization.

GAME - Greenfield AI Maturity Evaluation

GAME is our AI maturity diagnostic. It assesses an organization across seven dimensions and five levels, based on 90 minutes of interviews bringing together three to five key decision-makers (CIO or CDAO, business leadership, Risk & Compliance, executive management), followed by two to four weeks of analysis. The framework aligns with CMMI, ISO/IEC 42001, NIST AI RMF and CSRD.

GAME precedes transformation: it helps to inform and structure the investment decision, while highlighting the gaps between the different dimensions of transformation.

Certified Responsible Agentic - Governance of Agentic AI

Certified Responsible Agentic is the Meridian extension for the governance of AI agents. The framework articulates three distinct requirements: compliance, which translates the expectations of the standard; accountability, which designates the people personally answerable for the agent's decisions; and ethics, which covers fairness, explainability and the identification of impacted populations.

It cross-references our method with ISO 42001 and the European AI Act. A dedicated white paper is being finalized.

Our Transformation Package

Every engagement relies on a proprietary 150-page playbook covering the four operational dimensions of a transformation:

Financial Analysis: NPV, ROI, payback, investment model.
Business Analysis: use cases, requirements, business value.
Operating Model: roles, processes, target organization.
Change Management: sponsorship, training, embedding.

Within this package, Boldo allows us to map the Data, AI and governance capabilities of the organizations we support, and to align business and IT teams around the target architecture by sharing it with stakeholders.
